Thank you for the question.
Broadly speaking, we release income statistics at Statistics Canada annually. It's a pretty common pattern that household incomes—the incomes of families and individuals—are higher in western provinces, somewhere in the middle in Ontario and B.C., and lower in Quebec and the maritime provinces. That can be due to a lot of different things, including the types of work and work environments that are available. It also reflects the cost of living. It's often the case that many places in the Maritimes and in Quebec have a lower cost of living than some other places in Canada.
That's my first point, which is that the pattern we're seeing here among this particular group is fairly similar to the pattern we see in more aggregated statistics that concern the population overall.
My second point is that the low-income measure being used here doesn't take into account these differences in cost of living. It simply asks what proportion of Canadians in this province have an income that's low relative to the Canadian median, which means lower than most other people in the country. It doesn't take into consideration the cost of housing, food or transportation. Again, in those cases we often see that this particular low-income measure shows differences with other provinces and it sometimes shows higher levels.
Other measures, which aren't possible with this particular study—like the market basket measure, which does control for local costs—could show different results.
